🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Clear the glove box area

• Remove everything from the glove box so nothing falls out.
• Use a flashlight to locate the glove box sides and the small “damper” arm.
• Damper = the strap that slows the door.

Step 2: Remove the lower hush panel (under glove box)

• From the passenger footwell, remove the lower panel under the glove box.
• Use a 7mm socket, 1/4" ratchet, and 3" extension to remove any screws holding the panel.
• Use a trim panel removal tool to gently pop any retaining clips loose, then pull the panel down and out.
• When reinstalling these small interior screws: Torque to 2 Nm (18 in-lbs).

Step 3: Drop the glove box door fully

• Open the glove box.
• On the right side, detach the glove box damper arm.
• Use a trim panel removal tool to gently pry it off the pin if it’s tight.
• Push in on both glove box sides to release the “stops” (the plastic tabs that prevent it from falling open all the way).
• Lower the glove box down so you can access the filter door behind it.

Step 4: Remove the cabin filter access door

• Behind the glove box opening, find the rectangular cabin filter cover.
• Release the cover tabs by hand. If needed, use a trim panel removal tool carefully.
• Pull the cover off and set it aside.

Step 5: Remove the old cabin air filter

• Slide the filter straight out.
• Keep the filter level as you pull it out to avoid dumping debris.
• Tip: Vacuum loose leaves before installing new.

Step 6: Install the new cabin air filter

• Look for the airflow arrow on the filter frame.
• Install it in the same direction as the original (airflow arrow should match the housing’s airflow direction).
• Slide it in fully so it sits flat and doesn’t buckle.

Step 7: Reinstall the access door and glove box

• Reinstall the cabin filter cover and press until the tabs click.
• Lift the glove box back up and snap the side stops back into place by pushing the sides inward again.
• Reattach the damper arm on the right side by pressing it onto the pin.

Step 8: Reinstall the lower hush panel

• Position the panel, line up the clips, and press it into place by hand.
• Install any screws with a 7mm socket and 1/4" ratchet.
• Final tighten: Torque to 2 Nm (18 in-lbs).

✅ After Repair
